Months of aftershocks could follow big California earthquake

With the possibility of aftershocks and temperatures forecast to reach 100 degrees (38 Celsius) over the next several days, officials were taking precautions.

The California National Guard was sending 200 troops, logistical support and aircraft, said Maj. Gen. David Baldwin. The Pentagon had been notified, and the entire California Military Department was put on alert, he said.

Naval Air Weapons Station China Lake said in a Facebook post that nonessential workers were evacuated and operations halted.

The epicenters of both quakes were on the base, and officials said they are continuing to asses damage.

Officials said most employees live off the base, but they authorized the evacuation so those who live on base can be eligible for reimbursements.

The California Office of Emergency Services brought in cots, water and meals and set up cooling centers in the region, Director Mark Ghilarducci said.

State highway officials shut down a 30-mile (48-kilometer) section of State Route 178 between Ridgecrest and the town of Trona southwest of Death Valley, due to a rockslide and severe cracking.
